## Overview

The Extreme Max 3006.6652 Cube Anchor is a 19-pound zinc-plated alloy steel anchor designed for 18'-30' offshore and sport boats. Its innovative cube design sets instantly and self-adjusts to wind and current changes, providing superior hold without manual repositioning. When not in use, it folds flat for easy storage, making it the ultimate space-saving, reliable anchoring solution for freshwater boating.

## Description

For a quick grab and a maximum hold in offshore anchoring, set your eyes to the Extreme Max Cube Anchor! The unconventional design of a cube anchor shines where conventional-style anchors falter. No longer will you have to drag your anchor until you feel it hold or question whether or not it set, the cube anchor sets almost immediately upon impact and adjusts its hold and positioning in changing winds and currents without having to be manually maneuvered from the boat. When the parking is finished, the cube anchor quickly releases from the bottom and collapses flat to save space on your boat.

Review: Best anchor I have ever owned - I have looked at this anchor system for a couple years now. There are several manufacturers with varying prices but I settled on this system because of the lower than average price. I camp a lot and we take our 20' pontoon with us. During summers it's not uncommon to get fast moving thunderstorms and microburst while on the lake. There is also a tremendous about of boat traffic during the day which causes horrible waves that beat the boat against the shore. In the video above is my pontoon during a fast moving thunderstorm. This was the first true test of the system. Previously I had a 50lb dumbell tied to anchor chain and rope. The weight would hold the boat just fine but in a storm or heavy wave situation the boat would drag the anchor slightly. I have had sand anchors, drift anchors, mushroom anchors d homemade anchors. This is byfar the best anchor I have had. At this campsite the water is about 12"deep when you step off land and drops significantly as you go out with a mix of rocks, some sand but mostly fine silt. This area is on a point and the land is erosion protected by rocks and wrapped fencing so you have to make sure the anchor hold you off about 2' or your boat will be destroyed by waves pushing it I to the rocks. You can see in the video that this anchor held strong. I would give 6 stars if it was an option. Folds up for easy storage and is very easy to set up and set the anchor point. It really doesn't matter how you throw off the boat because it will correct itself and dig in quickly. Removing the anchor is easy as well. If you have a pontoon or any kind of boat that's heavy and needs a better anchor system do yourself a favor and buy this system. You will not regret it.
Review: Holds tight but did have to modify it. - Great anchor. Stores away nice and this thing really grabs. Did have to modify the locking pin by cutting it shorter because it couldn't lift high enough to clear and lock. It was definitely because of the way it was welder on there during manufacturing. But after that it worked great. Probably would of been mad if I wasn't a metal worker and didn't have the tools to fix it.
